Full-Wave Modeling and Inversion of UWB Radar Data for Wave Propagation in Cylindrical Objects
Remote Sensing, 2021 The nondestructive characterization of cylindrical objects is needed in many fields, such as medical diagnostics, tree trunk inspection, or concrete column testing. In this study, the radar equation of Lambot et al.

spyro: a Firedrake-based wave propagation and full-waveform-inversion finite-element solver [PDF]
Geoscientific Model Development, 2022 In this article, we introduce spyro, a software stack to solve wave propagation in heterogeneous domains and perform full waveform inversion (FWI) employing the finite-element framework from Firedrake, a high-level Python package for the automated ...

Rapid 4D FWI using a local wave solver [PDF]
, 2016 Much of the computational cost involved in full-waveform inversion comes from the solution of the wave equation in a large domain. These computations must be done for the entire domain through which we expect waves to pass for a particular survey ...

Controlling the stability transfer between oppositely traveling waves and standing waves by inversion-symmetry-breaking perturbations [PDF]
, 2006 The effect of an externally applied flow on symmetry degenerated waves propagating into opposite directions and standing waves that exchange stability with the traveling waves via mixed states is analyzed.
